Ontario Lacus is a lake filled with methane and ethane near the south pole of Saturn's moon Titan. It was identified as a hydrocarbon lake and confirmed by data from the Cassini spacecraft. This discovery was announced in the 31 July 2008 edition of Nature. Ontario Lacus is about 20,000 km² in area, and is named after Lake Ontario in North America, which is a similar size and shape.
